Abstract

The restoration performance and reliability of connections depend on that of the signaling communications network (SCN) in the automatically switched optical network.This paper analyzes the performance

transmission delay and reliability of the SCN and gets some important factors which affect the performance and reliability of the routing and signaling.Then

a planning scheme for the performance of the SCN based restoration time of the connection and a planning scheme for the reliability of the SCN based on single link-fault no-failure restoration are addressed.The planning scheme for the performance enables estimation of the restoration time for connection.The planning scheme for the reliability solves the issue of no-failure restoration on single link-fault and improves the ef ficiency of the broadcasting of routing information.
